In a group of nested loops, which loop is executed the most number of times?

  1. the outermost loop

  2. the innermost loop

  3. all loops are executed the same number of times

  4. cannot be determined without knowing the size of the loops


Correct Option: B

AI Explanation

To answer this question, we need to understand how nested loops work.

Nested loops are loops that are placed inside another loop. The number of times each loop is executed depends on the number of iterations of the outer loop.

Let's go through each option to understand why it is correct or incorrect:

Option A) the outermost loop - This option is incorrect. The outermost loop determines the total number of iterations, but it doesn't necessarily mean it will be executed the most number of times. The number of iterations of the outermost loop is dependent on the number of iterations of the inner loops.

Option B) the innermost loop - This option is correct. The innermost loop will be executed the most number of times because it goes through all of its iterations for each iteration of the outer loops. In other words, for each iteration of the outer loop, the innermost loop will execute all of its iterations.

Option C) all loops are executed the same number of times - This option is incorrect. The number of times each loop is executed depends on the number of iterations of the outer loop. Therefore, all loops are not executed the same number of times.

Option D) cannot be determined without knowing the size of the loops - This option is incorrect. The number of times each loop is executed can be determined based on the structure of the nested loops, regardless of the size of the loops.

The correct answer is B) the innermost loop. This option is correct because the innermost loop will be executed the most number of times as it goes through all of its iterations for each iteration of the outer loops.
